APPARATUS FOR INJECTING SALINE AND OTHER SOLUTIONS.

Specification of Letters Patent.

Patented Apr. 17, 1917.

Application filed June 8, 1914. Serial No. 843,651.

To all whom it may concern Be it known that I, Roscon SCOTT HAL- LOCK, a citizen of the United States, residing at Niles, in the county of Trumbull and State of Ohio, have invented a new and useful Apparatus for Injecting Saline and other Solutions, of which the following is a full, clear, and exact description, reference be ing had to the accompanying drawings, forming part of this specification, in which Figure l is a vertical section illustrating one form of apparatus embodying my invention.

Fig. 2 is a section on the line IIII of Fig. 1, and

Fig. 3 is a detail view of the pinching device.

My invention has relation to the injection of saline or other solutions into the human body through the rectum.

Saline solutions, when properly administered, are of great value in the treatment of various ailments, such as peritonitis, typhoid fever, pneumonia, auto-intoxication, general septicemia; and, in fact, any weakened or debilitated condition where there is either a high fever or 'a subnormal temperature. Some of the good effects of the saline are due to its action in flushing out the bowels and kidneys, increasing the fluids of the'body, stimulating the heart, etc.

In order to properly administer such solutions there should be a certain definite flow of the solution, regulated, both as to quantity and temperature, to the condition of the particular patient under treatment. For instance, some patients will stand a treatment of sixty drops per minute, while others will barely be able to retain over twenty drops per minute. In cases of very high temperature very little or no heat should be used, while in cases of normal or subnormal temperature, the saline should be maintained at from 100 to 110 degrees according to the effect desired.

Heretofore it has been common to give these drop by drop injections by means of an elevated reservoir having a regulating Valve, or by means of a visible glass dropper. In the use of the former, the flow is extremely irregular, since it tends to become less and less as the head decreases. Thus, a solution started at thirty drops to a minute may at the end of half an hour be flowing at the rate of twenty drops only, or less, or even not at all. The use of visible glass droppers is fairly satisfactory, but they are easily broken and thus put out of commission.

My invention provides means for administering saline or other solutions according to the drop by drop method in which any desired rate of flow may be obtained for any desired period of time, and at any desired temperature.

Referrin to the accompanying drawings in which I have illustrated the preferred. embodiment of my invention, the numeral 2 designates a suitable open supporting frame which can be suspended or otherwise supported at a height which will give the necessary head. 3 is a receptacle removably supported in the frame 2 and having a discharge nipple 4 at its lower portion. This nipple is, in the present instance, shown as adapted to receive a short piece 5 0f flexible tubing having a pinch clamp 6, by means of which the How therethrough can be regulated as may be desired. I may, however, provide the receptacle 3 with any suitable discharge and regulating valve.

7 designates a second receptacle supported below the receptacle 3 and which is pref crably closed at its upper portion by a removable cover 7 having therein an opening 8 through which the discharge from the tube 5 may enter the receptacle. At a suitable height above the bottom of the receptacle 7 is an outlet elbow 9 adapted for the reception at one end. of the usual flexible tube 10. This tube preferably has a thermometer 11 therein.

12- designates an electric lamp which extends within the liquid in the receptacle 7 for the purpose of heating such liquid to the desired temperature. 13 are the circuit wires for the lam controlled by the switch 14, mounted on the terminal box 15. Of course, more than one lamp may be employed, if necessary.

The operation will be apparent. The pinch clamp 6 is adjusted to discharge the required number of drops per minute, after the lower receptacle has been filled to about the overflow level. If it is desired to heat the solution the lamp 12 is lighted, and kept lighted sutliciently to maintain the desired temperature as indicated by the thermometer 11. Exactly the same amount of solution will overflow into the tube 10 as is received by the lower receptacle from the upper one. This insures the injection of a uniform amount of the solution throughout the pe riod of treatment.

Practical use of my invention has demon strated its great convenience and efliciency. It Will be obvious that my invention is sus ceptible to various changes in detail, and hence I do not Wish to limit myself to the particular embodiment thereof which I have herein shown and described.

ll claim:

1. Apparatus of the character described, comprising an upper receptacle open to the atmosphere and having a visible bottom discharge, a valve for regulating said discharge, a lower receptacle open to the atmosphere below said discharge and having an overflow opening, said overflow being below the discharge from the upper receptacle, so that the fluid passing from the one receptacle to the other is visible, a delivery tube connected to the overflow opening, and means Within the loWer receptacle for heating the liquid Within the lower receptacle, and which heated liquid passes out through the delivery tube, substantially as described.

2. Apparatus of the character described, comprising a portable frame, an upper reservoir receptacle removably supported therein, a lower receptacle arranged to receive the discharge from the reservoir receptacle, means for regulating the rapidity of such discharge, said lower receptacle having an overflow opening above its bottom, a delivery tube connected to said opening, an electric lamp within said receptacle below the overflow opening, and means for controlling said lamp, substantially as described.

In testimony whereof, I have hereunto set my hand.
